Gas separating |
December 25, 1990 |
| Feed gas is directed tangentially along the non-skin surface of gas separation membrane modules comprising a cylindrical bundle of parallel contiguous hollow fibers supported to allow feed gas to flow from an inlet at one end of a cylindrical housing through the bores of the bundled |

Tangential flow filtering and separating |
June 11, 1996 |
| A membrane cartridge has a feed inlet at one end and a retentate outlet at the other. Membrane structure of geometry defines a feed flow path and a permeate flow path between the feed inlet and retentate outlet. The cartridge has flow restrictions along the permeate flow path. |

Multiple head pumping |
August 21, 1990 |
| Membrane-based gas separation apparatus including a membrane separation device having a feed inlet and outlet and a permeant outlet, a motor, and at least two pump heads driven by the motor, one pump head being connected to supply a feed gas to the feed inlet and another pump head being |

Cartridge bonding |
February 6, 1990 |
| Membrane fibers extend into a potting compound that seals an end of the housing formed with openings in which the potting compound is seated, or through which a reinforcing pin passes. The end of the housing may be overlapped by a stepped portion of the potting compound. |

Anisotropic membranes for gas separation |
July 21, 1987 |
| A gas separation membrane has a dense separating layer about 10,000 Angstroms or less thick and a porous support layer 10 to 400 microns thick that is an integral unit with gradually and continuously decreasing pore size from the base of the support layer to the surface of the thin s |
